Permeability and chemical analysis of aromatic polyamide based membranes exposed to sodium hypochlorite

[Display omitted] ► Incorporation of chlorine on polyamide results in the weakening of intermolecular H bonds. ► Deconvolution of FTIR spectra provides experimental demonstration of this phenomenon. ► Packing propensity (during pure water filtration) is dominant above exposure to 400 ppm h HOCl. ► W...
